Hundreds more e-scooters are hitting Denver's sidewalks today, but the company is taking a markedly different approach than its rivals. Some might even call it a charm offensive. San Francisco-based Spin has approval from the city to deploy 350 scooters — the maximum allowed by law, and the same number competitors Lyft, Lime and Bird are each currently said to have scooting around Denver. But rather than flood the zone, Spin says it wants to ensure it understands the market before unleashing its full fleet. It's also making an effort to appeal to consumers, government and even bike-lane proponents.
